What is the next term in the sequence? 6, 11/2 , 5 , 9/2 , 4 What did you do to get your answer?

OpenStudy (amistre64):

what type of sequence are we looking at? arith. or geom?

OpenStudy (amistre64):

or random?

OpenStudy (anonymous):

It just says make a conjecture about the next item in each sequence

OpenStudy (amistre64):

$\frac{12,11,10,9,8,...}{2}$

OpenStudy (anonymous):

So I guess it's random

OpenStudy (anonymous):

${12 \over 2}, {11 \over 2}, {10 \over 2}, {9 \over 2}, {8 \over 2}, {{(13-n)} \over 2}={7 \over 2}$

OpenStudy (anonymous):

the only thing I know is that you subtract 1/2 and get the previous number, but I don't know how to get the next number

OpenStudy (amistre64):

its arithmetic, just have to make them all match denoms

OpenStudy (anonymous):

Oh I see

OpenStudy (amistre64):

if you know to subtract 1/2; then by all means do it

OpenStudy (anonymous):

Thanks

OpenStudy (anonymous):

Hey, but do you know a quick way of figuring this out?
